What this server can do
7 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
analyze_session(session_id)- Describe what is happening musically in a session — rhythm, pitch content, inferred key, and chords — without changing anything. Use this to explain music rather than to edit it. Results come from the same music-theory module the browser's Key Assistant and Chromatic Grid use, and report where the analysis is uncertain instead of guessing. Required: session_id.
create_session(name, tempo, idempotency_key)- Create a new editable Keyboardia session with the normal defaults and return its shareable URL. The session starts with no tracks; use edit_session to add them. Pass the same idempotency_key when retrying so an uncertain attempt cannot leave duplicate sessions behind. Required: idempotency_key.
edit_session(edit, session_id)- Make one narrow, retry-safe edit to an existing collaborative session. After every attempt, the next Keyboardia call must be get_session for the same session. A successful call includes a backwards-compatible compact snapshot plus an acknowledgement. That snapshot is not authoritative verification; do not make another edit or finish from it. Read with get_session next. Supported operations: add_track, set_track_instrument, set_track_pan, set_steps, and set_tempo. set_steps changes only the named steps; it never replaces a track or session. set_track_instrument replaces only a track's sound source, keeping its pattern, mix, timing, and custom name. Required: session_id, edit.
export_midi(session_id)- Export the session as a base64-encoded Standard MIDI File, matching what Keyboardia's own Export MIDI produces for the same music. The session is not modified. The result lists any session features a MIDI file cannot carry rather than approximating them silently. Required: session_id.
get_session(session_id)- Read the current tempo and compact track patterns from an existing Keyboardia session. Required: session_id.
publish_session(session_id)- Freeze the current music into a new immutable session and return its URL. The source session stays editable at its own URL. Only call this when someone explicitly asks to publish; it is never a side effect of editing or exporting. Required: session_id.
remix_session(session_id)- Copy an existing session — published or editable — into a new editable session that records the original as its source. The source is never modified, so this is how to continue from published work. Required: session_id.

Signals
These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
| Signal | Value | What it measures | Window | Observed | Source |
|---|---|---|---|---|---|
| GitHub stars | 3 | Number of GitHub accounts that bookmarked this repository since it was created. It is a bookmark count, not installs, not active users and not quality. | cumulative, all time | GitHub | |
| Last commit | 2026-08-04 | Date of the most recent push to any branch. This is the strongest cheap indicator of whether the project is still maintained. | point in time | GitHub | |
| Open issues | 7 | Open issues plus open pull requests, as GitHub counts them together. A high number can mean an active project or an abandoned one. | as of fetch | GitHub | |
| Latest published version | 1.1.0 | Latest version string the maintainer published to the registry. | as of fetch | Model Context Protocol | |
| Registry record last updated | 2026-07-31 | When the registry record was last updated by its maintainer. | point in time | Model Context Protocol | |
| License | MIT | Licence GitHub detected in the repository. Detection can be wrong; the LICENSE file is authoritative. | as of fetch | GitHub | |
| First listed in the MCP Registry | 2026-07-31 | Date this server was first published to the official MCP Registry. Not a usage or quality measure. | point in time | Model Context Protocol | |
| repository status | active | The repository exists on GitHub and is not archived. This says nothing about how recently it was worked on. | as of fetch | GitHub | |
| mcp tools declared | 7 tools | Number of functions the server itself declared when asked to list them. This is what the server offers an agent, not a measure of how well any of them work. | as of probe | keyboardia.dev | |
| mcp endpoint status | ok | The server listed 7 functions when asked. | as of probe | keyboardia.dev |
